Definitely take this question to textbroker, or re read the listing.
I agree that there are too many low ball bids out there for writing. I bid on projects for a respectable amount, sometimes willing to even go lower than my personal minimum if it is financially reasonable. The problem is too many writers are willing to sell their soul for $1 for a 500 word article. Unacceptable.
BTW... $.05 per word is a professional rate that is NOT found in content writing. At 5 cents per word you would be getting $25 for a 500 word article. I have been paid close to this for some projects, but not many people are willing to pay this if there are low ball bidders around.
